評估顏面整體對稱性的方法及評估系統

This invention discloses a method for evaluating the overall symmetry of a face, which is suitable for evaluating the symmetry of a face of a user. The method comprises the steps: shooting the face of the user by using a stereo imaging unit to obtain a stereo image data; calculating a plurality of first asymmetry indexes and a plurality of second asymmetry indexes by a processing unit according to the stereo image data, wherein the first asymmetry indexes are respectively correlated with a plurality of landmark points, the second asymmetry indexes are respectively correlated with a plurality of landmark point groups, and each of the landmark point groups comprises two paired landmark points; and calculating an overall face asymmetry index by the processing unit according to the first asymmetry indexes and the second asymmetry indexes, wherein the overall face asymmetry index is positively correlated with the first asymmetry indexes and the second asymmetry indexes.
